MASSENA--Arconic will soon begin a detailed environmental study at the Alcoa Continuous Mill site at Park Avenue East.

The investigation will define the nature and extent of contamination in soil and groundwater, and any other parts of the environment that may be affected, according to the state Department of Environmental Conservation.

Historical investigations at the site identified polychlorinated biphenyls (PCBs) contamination in soil and groundwater associated with aluminum wire manufacturing at the former plant.

The information collected during the investigation will be summarized in a report. After the site investigation is completed, the remedial party with oversight provided by NYSDEC will conduct a feasibility study.

This study uses information developed during the site investigation to develop and evaluate potential ways to clean up contamination related to the site.

The information collected may also support the conclusion that no action, or no further action, is needed to address site-related contamination.

NYSDEC will then develop a draft cleanup plan.

Public documents are available at the Massena Public Library, 41 Glenn St.
